For those as my good friend antonino61 that are looking for a smaller and/or portable Linux distro easy to install and capable to boot from a USB device as MBR/CSM and/or UEFI, the best option is PuppyLinux slacko64-7.0.iso (343 MB), just released on Jan/2021, the official page is: http://slacko7.eezy.xyz/
As all the good old Puppy Linux versions easier way to install is create a FAT-32 partition on our USB device or internal HD and just extact the ISO content on it, or at least the following files:
fdrv_slacko64_7.0.sfs
initrd.gz
puppy_slacko64_7.0.sfs
vmlinuz
zdrv_slacko64_7.0.sfs
And boot it as MBR/CSM by means of MBR grub4dos using the following entry on menu.lst:
title Boot slacko64-7.0\nRuns Puppy Linux Slacko64-7.0 from a partition on USB device
find --set-root /puppy_slacko64_7.0.sfs
kernel /vmlinuz pmedia=usbflash
initrd /initrd.gz
title Boot slacko64-7.0\nRuns Puppy Linux Slacko64-7.0 from a partition on internal HD
find --set-root /puppy_slacko64_7.0.sfs
kernel /vmlinuz pmedia=ataflash
initrd /initrd.gz
The first time we boot from it, when we turn off the OS it lets us create a persistence file to save there all changes we have done.
It can also be installed/extracted into a folder located on a partition of our USB device or internal HD, for more info see the included README.txt located into the ISO and just edit previous menu.lst entries as required.
Also the PuppyLinux slacko64-7.0.iso can be booted from Ventoy, see: https://www.ventoy.n...tro_iso/33.html
Haven't tested this yet, so I don't know if booting the ISO file with Ventoy we are able to create a persistence file.
This new version which is also capable to run on UEFI environment has integrated several frugal installers too, see: http://www.fishprogs...lpup/index.html
And better read the linked page carefully to avoid overwrite your EFI (FAT-32) partition on the internal HD:
Warning:
When using FrugalPup or DiskPup to install Puppy on a uefi computer with Windows already installed, it is not recommended to install Grub2 on the fat32 partition that contains the Windows boot. Grub2 should be installed on the first partition of some other bootable device, even if that is a small USB stick.
